3 What is ACTIV-8? ACTIV-8 Drier Accelerator and Stabilizer is a solution of 1,10-phenanthroline in n-butanol or hexylene glycol ACTIV-8 is NOT a drier 1,10-phenanthroline is a chelating agent ACTIV-8 works with cobalt and manganese driers to stabilize and accelerate the drying time

4 Typical Properties of ACTIV-8 ACTIV-8 Drier Accelerator Active Ingredient 1,10-phenanthroline (38 %) Solvents n-butanol (52 %) 2-ethylhexoic acid (10 %) Density 0.95 g/ml VOC 492 g/l (4.1 lbs/gal) ACTIV-8 accelerates and stabilizes the drying rates of solvent-borne and water-borne coatings that cure by oxidative polymerization

5 Typical Properties of ACTIV-8 HGL ACTIV-8 HGL Drier Accelerator Active Ingredient 1,10-phenanthroline (38 %) Solvent Hexylene glycol (62 %) Density VOC 1.03 g/ml 640 g/l (5.3 lbs/gal) ACTIV-8 HGL is a water miscible drier-accelerator The addition of ACTIV-8 HGL to the waterborne coating will inhibit the loss of dry

6 Alkyd Drying and Metallic Driers Alkyd coatings form a film and dry by an oxidative process Oxygen from the air cross-links the resin The oxygen up-take process is catalyzed by the presence of certain transition metals Cobalt (top drier) and manganese (through drier) are the most active metallic driers Additional metallic driers include zirconium, calcium, zinc, iron, and rare earths

7 Metallic Driers and ACTIV-8 ACTIV-8 Drier Accelerator chelates with cobalt and manganese, also with zinc and iron By the chelation, the most favorable valence state of the metal is maintained Beware of PINK AND ZINC Iron plus ACTIV-8 creates a strong pinkish/red colored complex Zinc plus ACTIV-8 forms an insoluble compound that does not aid in drying

8 Why use ACTIV-8? For the most consistent drying, a blend of driers and ACTIV-8 Drier Accelerator is recommended ACTIV-8 and cobalt is the most powerful drying combination In water-reducible alkyd coatings that use cobalt as the drier, ACTIV-8 HGL will prevent loss of dry

9 How much ACTIV-8 do I need? The general rule of thumb is: For solvent-borne alkyds use 10 parts (as supplied) of ACTIV-8 Drier Accelerator per 1 part of cobalt or manganese metal. For water-reducible alkyds use 5 parts (as supplied) of ACTIV-8 HGL per 1 part of cobalt metal. There are three steps to determining the amount of ACTIV-8 to use.

10 Step 1: Determine the amount of resin solids in the coating Determine the amount of resin solids in the coating Example: 195 kg of a 90% non-volatile solids alkyd resin solution contains: 195 kg x 0.90 = 175 kg of resin solids

11 Step 2: Determine the amount of metallic drier to use Driers are supplied as solutions of metallic salts of long chain organic acids in various solvents Their concentrations are expressed as % metal Recommended amounts of driers for air dry coatings are (based on resin solids): Cobalt % Manganese %

12 Step 2: Determine the amount of metallic drier to use Example: For the 175 kg of resin solids in Step 1, determine the amount of 12% cobalt solution that is equivalent to 0.05% 175 kg of resin solids x = kg of cobalt kg / 0.12 = kg of 12 % cobalt solution

13 Step 3: Determine the amount of ACTIV-8 Drier Accelerator to use. Determine the amount of ACTIV-8 Drier Accelerator to use Example: The kg of cobalt solution contains kg of cobalt metal kg x 10 = kg of ACTIV-8

18 Summary ACTIV-8 is NOT a drier ACTIV-8 is a drier accelerator Use ACTIV-8 with cobalt or manganese For solvent-borne alkyds use 10 parts ACTIV-8 per 1 part drier metal For water-reducible alkyds use 5 parts ACTIV-8 HGL per 1 part drier metal
